Definitions

  • the object of the invention is a supporting element for a tobacco industry machine used in a production machine for manufacturing tobacco, filter or multi-segment rods.
  • a continuous rod is manufactured which is cut during its movement into individual rods cut off from the continuous rod.
  • reciprocating mounted knives situated perpendicular to the axis of the manufactured continuous rod were used.
  • rotating knives which cut the continuous rod during the movement of the rod are commonly used.
  • the rotating knives are mounted to a rotating knife head whose axis is not parallel to the axis of the continuous rod. The inclination of the knife head and the special mounting of the knives make it possible to cut the continuous rod during movement.
  • the supporting element is made in the form of two sleeves having cutting surfaces directed opposite to each other, whereas the sleeves are situated coaxially and their cutting surfaces are spaced from each other at a distance equal to the thickness of the knife increased by a clearance.
  • the continuous rod is formed by wrapping the tobacco or filter material into a continuous wrapping material and gluing by means of an adhesive placed along the overlapping edges of the wrapping material.
  • the adhesive may deposit on the knife, and further the dirt from the knife may be transferred onto the supporting element, both onto the element in the form of closed cutting sleeves and open supporting elements.
  • the object of the invention is a supporting element for a tobacco industry machine designed to support a continuous rod moving axially during cutting by a rotationally mounted knife, whereas the supporting element comprises an at least partially cylindrical supporting surface for the continuous rod, having a longitudinal axis, moreover the supporting element has a front surface constituting a cutting surface, characterised in that the front surface has a depression.
  • the supporting element according to the invention is further characterised in that the depressed surface is parallel to the front surface.
  • the supporting element according to the invention is further characterised in that the depressed surface is situated at an angle to the front surface.
  • the supporting element according to the invention is further characterised in that the width of the depression is equal to or greater than the diameter of the cylindrical supporting surface.
  • the supporting element according to the invention is further characterised in that the outer part of the front surface is conical.
  • the supporting element according to the invention is further characterised in that the front surface is perpendicular to the longitudinal axis of the supporting surface.
  • the object of the invention is further a machine for manufacturing of rods in the tobacco industry provided with a feeding unit arranged to feed a filling material, a unit adapted to feed a wrapping material, a continuous rod forming unit, and a cutting unit provided with a rotating cutting head.
  • the machine according to the invention is characterised in that the cutting unit is provided with a supporting element according to the invention situated so that the axis of depression is directed convergently with the direction of movement of the knife mounted on the rotating head.
  • An advantage of the solution according to the invention is an increased quality of the tobacco, filter or multi-segment rods, in particular an improved cutting quality.
  • the application of depression according to the invention forms a removing channel which allows removing adhesive or other dirt generated in the course of production of the continuous rod or in the process of knife sharpening. As a result, such dirt does not get into a receiving sleeve and does not cause product degradation.
